Infineon AURIX TC3xx microcontroller family drives automated driving and electromobility



Serving Infineon Technologies’ AURIX TC3xx microcontroller line serves the requirements of automated cars and electric vehicles, offering six cores so real-time performance is three times higher than that available today.
With hexa-core architecture and advanced features for connectivity, security and embedded safety, the AURIX family TC3xx is facilitates a wide field of automotive applications. In addition to engine management and transmission control, powertrain applications include electrical and hybrid drive systems. Specifically, it handles hybrid domain control, inverter control, battery management, and DC-DC converters.
The AURIX TC3xx microcontrollers are well-suited to safety-critical applications ranging from airbag, braking and power steering to sensor-based systems using radar or cameras. The combination of performance and a powerful safety architecture can be beneficial for domain control and data fusion applications that support the next levels of automated driving.
The AURIX TC3xx family, which will be automotive qualified in 2019, will be highly scalable and offer Flash memory sizes of up to 16 MByte and more than 6 MByte of integrated RAM. Compared to today’s AURIX TC2xx microcontrollers with up to three TriCore cores, the TC3xx multicore architecture provides up to six TriCore cores, each with a full clock frequency of 300 MHz. Four of the six cores feature an additional lockstep core, enabling a new level of ISO 26262 functional safe computational power on a single integrated device. Up to 2,400 DMIPS performance supports applications classified ASIL-D. That performance more than triples the 740 DMIPS of the previous AURIX architecture.
The performance increase and the reuse of existing safety concepts allow automotive system suppliers to reduce development costs by 20 percent and improve time-to-market. Also, more functions can now be implemented on a single microcontroller, such as powertrain and chassis domain control and next generation radar and fusion algorithms.
Automotive radar systems ranging from blindspot monitoring to advanced front radar specifically benefit from the capabilities of the AURIX TC3xx family. TC3xx microcontrollers will feature a radar processing sub-system with up to two dedicated Signal Processing Units running at 300 MHz enabling computation of next-generation radar algorithms on a single chip. In addition, radar chips can be seamlessly connected to AURIX via a high-speed digital radar interface.
AURIX TC3xx addresses security with a programmable Hardware Security Module (HSM) available across the family. It supports secure on-board communications and preventa hardware manipulation such as motor tuning. New asymmetric cryptography accelerators are integrated into the HSM hardware to help achieve full EVITA support. The AURIX TC3xx facilitates fast software-over-the-air updates to protect against software hijacking.
As a host controller in gateway and telematics applications, AURIX TC3xx microcontrollers offer a Gigabit Ethernet interface, up to 12 CAN-FD channels compliant to ISO11898-1 and up to 24 LIN channels. An additional eMMC interface for external Flash interfacing enables local data storage supporting software-over-the-air update concepts.
